the tactic of putting two nuts on with one wrench holding the top nut on to keep pressure to lock the bottom nut into its position of sitting at the base of where the treading ends on these oem bolts as the bottom wrench attached to the bottom nut turns counter clockwise to loosen the bolt might not work i'm thinking. i'm wondering if there is a better way?
as well my question might be are my head studs 8mm? I've got a 80/66 bgf package. in al.fishermans breakdown of a china HT engine photo album he has the quote "Depending on model...6mm (same as both the intake and exhaust stud sizes) or 8mm." which means to me that if i don't have the same size studs in my exhaust and intake that i have 8mm head studs. My heads studs are clearly larger than the intake and exhaust. does anybody know if bgf 66/80cc engines have 1.0 or 1.25 thread pitch so i can go ahead and buy new ones from sick bike parts. i haven't removed them to put them side by side with the exhaust and intake studs to see if there the same which would mean they are 1.0 according to sick bike parts.
